ives looked into all the burton boards.. i need a twin shape board.. and they max they can hold is 86 . or 91 .. and i am 86. sooo shall i buy it?
i already broke a board.that holded 100 kg but it was a cheap one. will burton brake? like burton seven..

That board probably broke because it was cheap. If you are in the upper weight range for a board, basically all it means is that the board will be flexier and a little softer feeling than someone near the middle of the range.
